- Application filed September 5, 1917. Serial No. 189,848. g

To all whom it may concern: Be it known that I, JAMES H. MOKAY, a citizen of the United States, residing at Forest City, in the county of Winnebago and State of Iowa, have invented new and useful Improvements in Concrete Ties, of which the following is a specification. I

This invention relates to improvements in theconstruction of concrete ties for railway rails.

In carrying out my invention, it is my purpose to provide a tie comprising end members in the nature of reinforced concrete blocks, and connecting members for said end members in the nature of metallic rods. I

It is also my purpose to produce a tie comprising end members in the nature of blocks which have their under faces grooved longitudinally, and to provide connecting bars for the said blocks, the said bars being desi ed to be received in the grooves of the bloc {S and having integrally formed therewith, elements which contact with the opposite ends of the said blocks, whereby the rods and blocks may be quickly associated or disassociated as occasion requires.

It is a further object of the invention to produce a tie of this character which shall be of an extremely simple construction,

cheap to manufacture, and which will per-' form the functions for which it is devised with efficiency and with certainty.

Other objects and advantages will appear as the nature of the invention is more fully understood, reference being had to the accompanying drawings, in which,

Figure 1 is a perspective view of a tie constructed in accordance with the present invention, and illustrating the arrangement of rails on such ties.

Fig. 2 is a longitudinal sectional View taken in a line with one of the connecting bars for the ends of the ties.

Fig. 3 is a bottom plan view of one of the end members.

Fig. 4 is a perspective View of one of the connecting bars.

As disclosed by the drawings, the improved tie is primarily devised to engage with the rail 10 that has its foot or base portion formed with a flange or. rib 11, but, in this connection, it is to be stated that the tie may be provided with securing means whereby the rails of the ordinaryconstruction may be attached thereto.

The tie comprises essentially end members 12 and connecting members 13 for the said end members. The end members 12, in the present instance, are in the nature of reinforced plastic blocks, certain of the reinforcements, indicated for, distinction by Specification of Letters Patent. Patentd *Dec'. 11, 1917.

the numeral 14, having upset ends and being disposed approximately central and longi tudinally of the saidblocks 12 and directly below transverse slots 15 in the said block which receive the referred to ribs or flanges 11 of the rails 10.

The blocks 12, upon their under faces are provided with longitudinal grooves 16 of a width to snugly receive the connecting members 13. The connecting members are preferably in the natureof metallic bars, which, of course, embody a certain resiliency, the said bars at their ends being upset as at 16,

the said upset portions contacting with the to efiectively retain'the same, by virtue of.

such contactin aproper position upon the members 13. 1

From the foregoing description, when taken in connection with the drawing, the simplicity and advantages of the construc tion will be apparent without further detailed description.-

Having thus described the invention, what I claim is:

1. In a tie for railway rails, blocks having their under faces grooved longitudinally, connecting bars for said blocks received in the referred grooves and having elements integral therewith engaging the ends of the said blocks. r

2. Ina railway tie, reinforced plastic blocks forming rail seats and having their under faces grooved longitudinally, connecting bars for the blocks received in the referred to grooves, said bars having their ends upset to engage with the outer ends of the blocks, said bars being further provided with additional upset portions designed to engage with the inner ends of the said blocks.

-3. In a railway tie, plastic blocks having transverse slots in the upper faces thereof, said blocks having their under faces grooved throughout the length thereof, metallic connecting bars for the blocks received in the grooves thereof, said bars having their ends upset to engage With the outer ends of the blocks and to exert a spring tension against said ends, and said bars being provided with additional upset portions designed to engage the inner ends of the blocks and to 10 exert a spring tension thereagainst.

1 intestimony whereof I affix my signature.
